FLEXIBLE CIRCUIT BOARD

摘要

A flexible circuit board (15) including a flexible substrate (15) having an insulating polyimide sheet and a wiring pattern portion (16a,16b) formed in a mounting portion (11a) and a wiring pattern portion formed in a connecting portion (11b), and a metal substrate (12) on which only the mounting portion (11a) of the flexible substrate (15) is secured by means of a thermoplastic polyimide film (14). Electronic devices (13a, 13b) are mounted on the mounting portion (11a) of the flexible substrate (15). The connection portion (11b) of the flexible substrate (15) can be connected to an external circuit by means of a connector (18) provided at an edge of the connecting portion.
